Lateral movement is the phase of an attack that most security tools were never built to see. Once an adversary clears the perimeter, they pivot quietly between systems using valid credentials, native protocols, and legitimate administrative tools. In a hybrid environment, where on-premises Active Directory connects to a cloud identity provider like Microsoft Entra ID, and workloads span AWS, Azure, and private data centers at the same time, that pivot crosses infrastructure boundaries without triggering a single alert.

enhanced.io is a channel-only Open XDR SOCaaS built exclusively for MSPs, with 400+ integrations across endpoint, network, cloud, identity and IoT/OT. This article explains how the platform closes the lateral movement gap specifically, layer by layer.

The numbers show the scale of the problem. According to Illumio's 2025 Global Cloud Detection and Response Report, based on a survey of 1,150 cybersecurity leaders, nearly 90% of organizations experienced a security incident involving lateral movement in the past year, and each incident averaged more than 7 hours of downtime. Gigamon's 2024 Hybrid Cloud Security Survey found that 96% of lateral movement does not trigger alerts in traditional security tools at all.

Most security stacks were designed around north-south traffic, the traffic crossing the network perimeter. Lateral movement happens east-west, between internal systems, where firewalls and endpoint agents have limited or no visibility. That's the structural gap enhanced.io was built to close.

Why hybrid cloud makes lateral movement harder to detect

Hybrid cloud environments are not simply cloud plus on-premises. They're environments where identity, authentication, and workload trust are deeply interconnected across infrastructure that was designed independently and integrated over time. That interconnection is operationally valuable, and it's exactly what attackers exploit.

The identity bridge problem

In most hybrid environments, on-premises Active Directory synchronizes with a cloud identity provider through a tool like Microsoft Entra Connect. This synchronization server is one of the most privileged objects in the entire environment. It holds credentials that read and write to both AD and Entra ID at the same time. Compromise that server, and an attacker forges federated identity tokens, adds malicious domains to the tenant, or escalates privileges across both environments without touching a traditional "hacking" tool.

MITRE ATT&CK Tactic TA0008 documents specific hybrid lateral movement techniques including T1078.004 (Cloud Accounts) and T1021.007 (Cloud Services), where adversaries use accounts synchronized from on-premises to reach cloud-hosted resources. These techniques are difficult to detect because the authentication events look entirely legitimate to any tool that only monitors one environment.

The east-west visibility gap

The second structural problem is network visibility. Perimeter security tools, firewalls, IDS/IPS systems, and web gateways were built to inspect north-south traffic: packets entering and leaving the network. They're blind to east-west traffic by design. In a hybrid cloud environment, east-west traffic flows between:

• On-premises servers communicating with cloud workloads via VPN or ExpressRoute

• Virtual machines within the same cloud VPC or VNET

• Container-to-container communication within Kubernetes clusters

• IoT and OT devices communicating with management systems

Endpoint detection and response agents observe some of this traffic from the perspective of a managed endpoint, but they don't see both sides of a session at once, provide no coverage for unmanaged devices, and don't monitor network-layer protocol patterns at scale.

The result: nearly 40% of east-west traffic in hybrid environments lacks sufficient context for confident investigation, according to the Illumio 2025 report. Security teams are monitoring, but not seeing.

Alert fatigue compounds the problem

The visibility gap creates a second problem: alert fatigue. The same Illumio research found that 67% of security teams receive more alerts than they are able to effectively investigate, averaging over 2,000 alerts a day. When a team is unable to distinguish signal from noise, lateral movement has time to progress. The average time to detect an issue caused by a missed alert is 12.1 hours. That's enough time for an attacker to move from initial foothold to domain controller access.

How enhanced.io detects lateral movement across hybrid environments

enhanced.io addresses lateral movement through its Open XDR architecture, which aggregates telemetry from across the entire hybrid environment rather than relying on any single detection layer. The platform integrates with over 400 security and IT tools, so MSP partners don't need to rip and replace an existing stack to gain this visibility. The detection capability operates across four interconnected layers.

Layer 1: east-west network traffic monitoring

enhanced.io ingests network flow data from across the hybrid environment, including VPC flow logs from AWS and Azure, on-premises network taps, and traffic metadata from cloud workloads. That gives the platform continuous visibility into the traffic perimeter tools are unable to see.

The platform correlates this network telemetry against behavioral baselines for every device, subnet, and workload. Deviations from normal east-west patterns, a workload that suddenly initiates SMB connections to systems it has never communicated with, or a cloud VM beginning to scan internal subnets, get flagged for investigation. This isn't signature matching. Lateral movement using valid credentials and native tools leaves no signature to match. The detection is behavioral.

Layer 2: identity and authentication correlation

Because the identity bridge between on-premises AD and cloud identity providers is the highest-value lateral movement path in hybrid environments, enhanced.io treats identity telemetry as a first-class detection domain. The platform correlates:

These signals are mapped to MITRE ATT&CK techniques and enriched with asset criticality context. The same technique generates a different alert severity depending on whether the affected system is a developer workstation or a domain controller adjacent to a financial database.

Layer 3: IoT, OT, and unmanaged device visibility

One of the most significant lateral movement blind spots in traditional security stacks is unmanaged devices. IoT sensors, OT systems, and legacy infrastructure that are unable to run EDR agents are invisible to endpoint-centric detection. Attackers know this and frequently use these devices as pivot points.

enhanced.io's Open XDR architecture extends visibility to non-agent surfaces through network-level telemetry and integrations with specialist OT/IoT data sources. This is a core differentiator. The platform was designed from the ground up to monitor the surfaces agent-based tools are unable to reach.

Layer 4: cross-environment behavioral analytics

Lateral movement in hybrid environments rarely triggers detection when viewed through a single telemetry source. A suspicious Kerberos ticket request on-premises looks unremarkable in isolation. Pair it with an unusual AssumeRole event in AWS CloudTrail 20 minutes later, and the picture changes entirely.

enhanced.io's behavioral analytics engine correlates signals across on-premises logs, cloud audit trails, identity provider events, and network telemetry into a unified investigation timeline. This cross-domain correlation is what separates a platform that generates alerts from a platform that surfaces incidents. The NCSC's guidance on network monitoring and CISA's Zero Trust Maturity Model both point to this kind of correlated, context-rich visibility as the foundation of effective threat detection.

From detection to mitigation: the SOC response layer

Detection without response is a monitoring dashboard, not a security program. The reason lateral movement causes so much damage isn't that it's undetectable in principle, it's that most organizations lack the analyst capacity to act on detections fast enough. The NCSC notes that effective security monitoring needs a defined process for triage and response, not only collection and alerting.

enhanced.io closes this gap through its 24/7 SOC operations, built directly into the platform delivery model for MSP partners.

Containment actions mapped to attack progression

When the enhanced.io SOC identifies lateral movement activity, response actions are prioritized based on where the attacker is in the kill chain and which assets are at risk. The response framework runs in three phases.

1. Triage and confirmation. The SOC analyst reviews the correlated alert, validates the detection against behavioral baselines, and rules out false positives. This step matters: security teams waste an average of 14.1 hours a week chasing false positives, according to Illumio's 2025 research. enhanced.io's context-enriched alerts reduce this burden by surfacing only high-confidence detections with full investigation context already attached.

2. Isolation and containment. Confirmed lateral movement triggers immediate containment actions. Depending on the technique and affected systems, this includes account suspension, network segmentation enforcement, endpoint isolation, or cloud identity token revocation. The goal is to interrupt the attacker's movement path before they reach high-value assets.

3. Remediation and hardening. After containment, the SOC works with the MSP partner to close the vulnerability exploited in the attack. This might involve credential rotation, policy tightening, segmentation rule updates, or configuration changes to the identity bridge. The Fractional Security Director assigned to every enhanced.io partner plays an active role here, translating technical findings into remediation guidance the MSP puts to use.

Why 24/7 coverage matters specifically for lateral movement

Lateral movement doesn't respect business hours. Attackers often start post-compromise activity at night or over weekends, precisely because SOC teams are understaffed during those windows. A detection that fires at 2am on a Saturday is worthless without an analyst ready to act on it.

enhanced.io's SOC-as-a-Service model provides continuous coverage, so MSP partners and their clients are protected regardless of when an incident begins. This matters particularly for MSPs serving regulated industries, where compliance frameworks including NIST SP 800-171, CMMC, NIS2, and DORA all require demonstrable incident response capability, not only detection tooling.

Detection is necessary but not sufficient. The combination of behavioral analytics that surface high-confidence lateral movement signals, and a 24/7 SOC that acts on them within minutes, is what stops attacks from progressing in practice.

The MSP advantage: delivering lateral movement protection at scale

For MSPs and MSSPs, the challenge of lateral movement protection is compounded by the need to deliver it consistently across dozens or hundreds of client environments, each with a different hybrid cloud architecture, a different mix of tools, and a different risk profile.

enhanced.io's channel-only model was designed around exactly this challenge. A few capabilities make it practical to deliver lateral movement protection at MSP scale.

No rip-and-replace integration

Because enhanced.io integrates with over 400 security and IT tools, MSPs layer its Open XDR capabilities on top of the tools clients already have deployed. The platform ingests telemetry from existing SIEMs, EDR solutions, firewall logs, and cloud-native security services, consolidating it into a unified detection layer. That matters commercially: clients don't need to invest in replacing existing infrastructure to gain the lateral movement visibility they're currently missing.

Flexible delivery models

MSPs serving clients with different maturity levels deploy enhanced.io across three models:

This flexibility lets MSPs match the delivery model to each client's budget and risk tolerance without maintaining separate tooling for different tiers.

Compliance reporting built in

Lateral movement incidents aren't only operational events, they're compliance events. Clients subject to CMMC, NIS2, DORA, or Essential Eight face reporting obligations when security incidents occur. enhanced.io's platform includes compliance reporting mapped to these frameworks, so MSPs deliver the documentation their clients need without building a separate reporting workflow.

The strategic value for MSPs is straightforward: the ability to demonstrate comprehensive lateral movement detection and response capability, backed by 24/7 SOC coverage and compliance-ready reporting, is a real differentiator in a market where many clients are unable to distinguish between vendors offering superficially similar services.

Closing the gap before the attacker reaches the crown jewels

The data is unambiguous. Lateral movement is the defining challenge of hybrid cloud security right now. Nearly every organization has experienced it. Most have inadequate visibility into where it happens. And the tools many teams rely on, perimeter firewalls and endpoint agents, were not designed to detect it.

The answer isn't more tools. It's the right architecture. Effective lateral movement detection needs continuous east-west network visibility, identity telemetry correlated across on-premises and cloud environments, coverage for unmanaged devices, and the analyst capacity to act on detections before attackers reach critical systems.
